Design Objectives
The ocean is an extremely demanding environment that, to ensure the survivability and cost-effective operation of any technology, requires careful attention to several design parameters. Resolute expects its Wave2OTM technology will be widely adopted because its design objectives are focused on features that deliver tangible benefits to our customers including:

  • simplicity - fewer parts subject to wear/breakage. All complex systems positioned onshore
  • modularity - fits any size power need & easy to maintain
  • adaptability - adjusts to different wave climates without excessive customization
  • small size - minimizes transportation/installation/retrieval costs and virtually eliminates service interruptions

RME’s testing program has validated our design strategy and as a result we expect to achieve sustainable competitive advantages related to lower up-front capital cost, lower operation & maintenance costs and significant potential for profit margin expansion when our Wave2OTM systems are manufactured in larger numbers.

Technology Development Milestones
In January 2009, RME conducted sea trials of an early point-absorber wave energy converter (WEC) prototype pursuant to a NOAA-funded project to develop a renewable energy power supply for offshore aquaculture systems. Since then, RME has been focused on developing a near-shore, bottom-mounted hinged flap design with R&D funding provided primarily by the U.S. Department of Energy. We feel this WEC type is ideal for several reasons:

  • As a near-shore (shallow water) technology, less of the total project cost is devoted to the transmission system (hoses and cables) that carries pressurized seawater and data from the WECs to shore
  • As a WEC technology that is fixed directly to the seabed:
    • there are no mooring lines that can become entangled or entrap marine wildlife;
    • the WEC(s) are not exposed to the extreme loads present at the surface during severe storms and in “full protection” mode, the flaps can be locked down flat.

Since its founding in 2007 Resolute has been developing and validating proprietary hydrodynamic modeling tools with assistance from researchers at MIT and have conducted several rounds of scale-model tests at Alden Labs in Massachusetts and at the Bureau of Ocean Energy Management (BOEM) wave tank in New Jersey.  In addition, we have conducted two rounds of ocean trials on the Outer Banks of North Carolina with the cooperation and assistance of the University of North Carolina Coastal Studies Institute (UNC-CSI) and the U.S. Army Corps of Engineers (USACE). More recently, we conducted extreme load tests at a wave tank facility in Inverness, Scotland and have been engaged in a multi-year, DOE-funded program focused on developing an advanced control system that maximizes WEC power output while coordinating the water production process in response to wave resource conditions. We were recently awarded a Phase I SBIR grant and we have submitted several grant proposals in Europe that are in the final stages of evaluation.

Intellectual Property
RME has been steadily building the value of its IP portfolio over many years and will consider other options including licensing and acquisitions of patents and patent portfolios.
